Dugongi's origin trial feedback

[rallu]

I develop Dugongi, an application for recording and animating videos and sharing them in real-time.

I have been participating in the Captured Surface Control origin trial. The API provides the functionality I need. (It would have been great to forward click events.)

• With respect to ongoing discussions about the API shape, here are some of my application's requirements:
  My application renders incoming video streams on a canvas that users can draw on top of. I forward the scrolling events from the canvas to the shared tab.
• Over the past 25 years of Web development, it has become quite clear to me that users rarely notice the browser's own controls. Implementing zoom controls to next to my other controls of the stream (like of crop and rotate) is much more preferred.
